Chlorine is a foundational chemical widely utilized in the manufacturing of commercial bleaches, disinfectants, polyvinyl chloride (PVC), and numerous organic intermediates. However, due to its extremely high oxidizing potential, chlorine is exceedingly dangerous, poisonous, and highly corrosive. This corrosivity is severely amplified in the presence of moisture, which leads to the rapid formation of destructive hydrochloric and hypochlorous acids. Consequently, analyzing trace impurities in such a harsh gas matrix requires highly specialized instrumentation designed to prevent catastrophic hardware failure.
To decisively overcome these severe operational challenges, the GAS Impurities in Chlorine Analyser is constructed exclusively with highly resilient wetted parts, including Hastelloy-C, Dursan-coated components, and advanced co-polymers. Furthermore, the system incorporates an intelligent, highly inert flush valve that immediately purges the entire sample pathway post-injection, drastically minimizing chlorine contact time and preventing acid formation. The analyzer utilizes a highly efficient dual-channel architecture: a primary permanent gas channel utilizing Helium carrier gas to quantify O₂, N₂, CH₄, CO, and CO₂, alongside a secondary channel equipped with Argon or Nitrogen carrier gas dedicated specifically to Hydrogen and Helium detection.
